Microservices, that is, breaking larger applications into small parts that communicate over APIs, is increasingly becoming the architectural style of choice for many developers (especially when coupled with containers). Managing this fleet of services introduces its own set of challenges, though. To help developers and DevOps professionals manage and secure their microservice-based applications, Google, IBM and Lyft today announced Istio, a new open platform that allows you to create a network of deployed services, and which includes tools for load balancing, service-to-service authentication and monitoring, among others.
It can do all of this without requiring any changes to the actual applications.

At its core, Istio uses the Envoy proxy (which was developed by Lyft) and its built-in service discovery and load balancing tools, among other things.
